320x480 does not work, not does any other combination of size that maintains that precise aspect ratio (e.g. 160x240). However, if I change the ratio slightly, say by adding or subtracting 16 from the width, it plays fine. Odd.
I'll have a look at the source and see if I can tell what's up. Thanks. On Nov 12, 9:30 am, Dave <[EMAIL PROTECTED]> wrote: > I've never tried 320x480 but it should work.
